Furthermore, in describing the present invention, specific descriptions of known functions or configurations may be omitted to clarify the gist of the present invention. FIG. 1 is a photograph showing the first body and the second body of a rifle separated from each other according to one embodiment of the present invention. FIG. 2 is an enlarged photograph of the fastening part of a rifle according to one embodiment of the present invention. Referring to FIGS. 1 and 2, the rifle of the present embodiment may include a first body (100), a second body (300), and a fastening part (500). The fastening part (500) of the present embodiment may securely connect the first body (100) and the second body (300) to each other so that the first body (100) and the second body (300) do not separate during use. At this time, the fastening part (500) includes a rotating plate (590, see FIG. 5) and a coil spring (520, see FIG. 5), and the coil spring (520) may apply force to the rotating plate (590) so that the rotating plate (590) faces the first body (100). The rifle of the present embodiment can be separated into a first body (100) and a second body (300). Additionally, the first body (100) and the second body (300) can rotate around a second rotation axis (700). At this time, the first body (100) and the second body (300) can be hinge-connected to each other. In the rifle according to the present embodiment, the first body (100) and the second body (300) can be fixedly coupled to each other during firing. However, when repairing or inspecting the rifle according to the present embodiment, the first body (100) can be rotated relative to the second body (300) around the second rotation axis (700) to separate them. When the first body (100) and the second body (300) are separated from each other, the chamber, etc., inside the first body (100) can be repaired or inspected. The first body (100) may include a barrel, a barrel cover, a front sight, etc. The barrel is a metal tube through which a bullet passes when fired, and the barrel is covered by a barrel cover. The front sight is located on the upper part of the first body and is a sighting device capable of aligning the barrel with a target. The second body (300) is combined with the first body (100) and may include a magazine, a handle, a trigger, a stock, etc. The magazine may supply bullets fired through the barrel, and the handle may be configured to firmly grip the hand when pulling the trigger. The stock is a part attached to the user's shoulder and may serve to absorb the recoil of the chamber explosion. The above fastening part (500) can fix the first body (100) and the second body (300) to each other or separate the first body (100) and the second body (300) from each other. According to the present embodiment, depending on the position of the fastening part (500), the first body (100) and the second body (300) can be fixed or separated from each other. FIGS. 3 and FIGS. 4 are drawings illustrating the operation of a fastening part for separating the first body and the second body of a rifle. Referring to FIGS. 3 and FIGS. 4, the fastening part (500) may include a support pin (510), a support body (550), an insertion projection (570), and a second coil spring (530). The support pin (510) may be extended parallel to the barrel extending along the first direction (X-axis). The support pin (510) may have a cylindrical shape. However, the shape of the support pin (510) is not limited thereto and may be a square prism or a polygonal prism having a polygonal cross-section. A second coil spring (530) may be coupled to the support pin (510). More specifically, the second coil spring (530) may be positioned to surround the outer surface of the support pin (510). At this time, the support body (550), which will be described later, may be directed to the right by the second coil spring (530). If the user does not push the support body (550) to the left, the support body (550) may come into contact with the second body (300) located on the right by the second coil spring (530). A support body (550) may be attached to the end of the support pin (510). A portion of the upper side of the support body (550) may be exposed outside the first body (100). By moving the exposed support body (550) to the left along the first direction (X-axis), the support pin (510) and the insertion projection (570) attached to the support body (550) can be moved to the left simultaneously. At this time, an uneven surface may be formed on the upper surface of the exposed support body (550) (see FIG. 2). When a user pushes the upper surface of the exposed support body (550) to move the support body (550) to the left, the user's hand may be prevented from sliding on the upper surface of the support body (550). An insertion projection (570) may be disposed at one end of the support body (550). The insertion projection (570) may protrude in the opposite direction to the support pin (510) with respect to the support body (550). That is, the insertion projection (570) may be formed to protrude toward the second body (300). According to the present embodiment, the insertion projection (570) can be inserted into a receiving groove (not shown) formed in the second body (300). At this time, the insertion projection (570) may have a shape corresponding to the shape of the receiving groove of the second body (300). Referring to FIG. 3, when the first body (100) and the second body (300) are fixedly coupled to each other, the insertion projection (570) can be inserted into a receiving groove (not shown) of the second body (300). By inserting the insertion projection (570) into the receiving groove (not shown), the first body (100) or the second body (300) can be prevented from rotating around the second rotation axis (700). Referring to FIG. 4, when the first body (100) and the second body (300) are separated from each other, the insertion projection (570) can be moved to the left so that the insertion projection (570) can be separated from the receiving groove (not shown). By doing so, the first body (100) or the second body (300) can rotate around the second rotation axis (700). That is, the first body (100) and the second body (300) can be separated from each other. FIGS. 5 and 6 are drawings illustrating the operating state of a rotating plate of a rifle according to one embodiment of the present invention. Referring to FIGS. 5 and FIGS. 6, in this embodiment, during use, the first body (100) and
[0042] To prevent the second body (300) from being separated from each other, the first body (100) and the second body (300) can be joined or separated from each other by a fastening part (500). The above fastening part (500) may include a rotating plate (590) and a coil spring (520). The above-mentioned rotating plate (590) may be placed within a cut groove (557, see FIG. 2) formed on the upper side of the support body (550). The rotating plate (590) may rotate around a first rotation axis (580). At this time, the first rotation axis may be parallel to a second direction (Z-axis) that intersects a first direction (X-axis). The above-mentioned rotating plate (590) may include a first projection (593) and a second projection (595). The first projection (593) may extend along the radial direction from the center of the rotating plate (590) through which the first rotation axis (580) passes. The second projection (595) also extends along the radial direction from the center of the rotating plate (590), and the second projection (595) may form a predetermined angle with the first projection (593). At this time, the predetermined angle may be greater than 0 degrees and less than 90 degrees. That is, the first projection (593) and the second projection (595) of the rotating plate (590) can rotate clockwise or counterclockwise around the first rotation axis (580) while forming a predetermined angle. At this time, the first projection (593) can act as a stopper to block the fastening part (500) from moving to the left along the first direction (X-axis). As illustrated in FIG. 5, when the first projection (593) of the rotating plate (590) is positioned at approximately the 9 o'clock direction, the first projection (593) and the first body (100) are placed in contact with each other, so the support body (550), insertion projection (570), etc. cannot move to the left. That is, the insertion projection (570) cannot be separated from the receiving groove (not shown) of the second body (300), so the first body (100) and the second body (300) cannot be separated from each other. Meanwhile, the second projection (595) can act as a lever to change the position of the first projection (593). When the user rotates the second projection (595) clockwise, the position of the first projection (593) can be changed from the 9 o'clock position to the 12 o'clock position. Conversely, if the user rotates the second projection (595) counterclockwise, the position of the first projection (593) can be changed from the 12 o'clock direction to the 9 o'clock direction. Additionally, it includes a coil spring (520) that applies force in one direction to the rotating plate (590) which rotates around a first rotation axis (580) parallel to the second direction intersecting the first direction, and one end of the coil spring (520) is inserted and fixed to the rotating plate (590), and the other end of the coil spring (520) is inserted and fixed to the support body (550). The other end of the coil spring (520) is inserted and fixed to a fixing member (521) installed on the upper part of the support body (550). Referring to FIG. 6, when the user rotates the second projection (595) clockwise, the first projection (593) is positioned from the 9 o'clock direction to the 12 o'clock direction, allowing the support body (550) and the insertion projection (570), etc., to move to the left. As a result, the insertion projection (570) is separated from the receiving groove (not shown) of the second body (300), and the first body (100) and the second body (300) can be separated from each other. FIG. 7 is a drawing illustrating a coil spring of a rotating plate according to an embodiment of the present invention. FIG. 8 is a drawing illustrating a spring guide and a fixing member of a coil spring according to an embodiment of the present invention. Referring to FIGS. 7 and 8, the rifle includes a coil spring (520) that applies force in one direction to a rotating plate (590) that rotates around a first rotation axis (580) parallel to a second direction that intersects the first direction. One end of the coil spring (520) is inserted and fixed to the rotating plate (590), and the other end of the coil spring (520) is inserted and fixed to the support body (550). In one embodiment, the other end of the coil spring (520) is inserted and fixed to a fixing member (521) installed on the upper part of a support body (550), and the coil spring (520) is inserted and fixed to a spring guide (522) installed on a first rotation axis (580). Since the body of the coil spring (520) is fixed in a state where it is inserted into the spring guide (522), the rotating plate (590) can be operated in a more stable state. Accordingly, in the rifle of the present embodiment, unless the user artificially rotates the rotating plate (590) clockwise, the first projection (593) of the rotating plate (590) always comes into contact with the first body (100) by the coil spring (520), thereby preventing the first body (100) and the second body (300) from separating from each other. Although the present invention has been illustrated and described above in relation to preferred embodiments to illustrate the principles of the invention, the invention is not limited to the configuration and operation as illustrated and described. Rather, those skilled in the art will understand that numerous changes and modifications to the invention are possible without departing from the spirit and scope of the appended claims.
